FormatFeature (jackson-core 2.9.2)

```
public interface FormatFeature
```
Marker interface that is to be implemented by data format - specific features. Interface used since Java Enums can not extend classes or other Enums, but they can implement interfaces; and as such we may be able to use limited amount of generic functionality.
Note that this type is only implemented by non-JSON formats: types JsonParser.Feature and JsonGenerator.Feature do NOT implement it. This is to make it easier to avoid ambiguity with method calls.

Since:

2.6 (to be fully used in 2.7 and beyond)
